What happened
Anthropic asked a federal appeals court in Washington, D.C. to rehear its appeal over the Pentagon's blacklisting of the company's AI models, CNBC reported on October 13, 2026. The request came after the D.C. Circuit upheld the Defense Department's decision in September. The case concerns the Pentagon's treatment of Anthropic's AI models and the company's attempt to reverse it in court.
The Defense Department labeled Anthropic a supply chain risk in March, and the company sued the Trump administration in an effort to undo that action. The rehearing request was the company's next step in that dispute after the September decision. CNBC's opening summary of the case did not describe the arguments in Anthropic's filing, any response from the Pentagon, or when the court might decide whether to rehear the case. It gave no contract values, revenue figures or other financial amounts tied to the designation, and it did not say how the label affected Anthropic's government business.

Why it matters
The supply chain risk label is still being contested after the September loss, so the company's exposure on the Pentagon side remains open. The source does not describe its financial effect.
The designation concerns the Pentagon's treatment of Anthropic's AI models. How it affects defense revenue is not stated in the source.
The report gives no monetary figure, so the dispute adds a legal risk to the picture of the business but not a measurable change to value.
